Fish Presentation
  • Introduce Myself
  • The FODC Mission
  • The Grandma Rule
  • My Goal for the upper Mon basin
  • Fishes and the Big Picture
  • Fishes and Deckers Creek
  • A Fish Plan for Deckers Creek

4
FODC Mission
  • to improve the natural qualities of,
  • to increase public concern for, and
  • to promote the enjoyment of
  • the Deckers Creek watershed

5
The Grandma Rule
  • Reason for cleaning up a river should be obvious
    to my grandma in one sentence.

6
My Goal for the Upper Mon
  • Recover waterbodies that support self-sustaining
    aquatic communities and provide quality
    opportunities for fishing and other forms of
    recreation for residents of and visitors to the
    region.

7
I am not against fish stocking as a form of
fisheries management
8
I am against depending on stocking as a means of
meeting water quality and fisheries objectives
  • Inefficient
  • Costly (fuel, food, manpower)
  • Unsustainable
  • Misleading / Misdirected Effort

9
Fishes and the Big Picture
  • 41 of fish species are freshwater (10,500
    worldwide) despite freshwater being only 0.01 of
    all water (importance of isolation and habitat
    diversity)
  • 950 species in N.A. (75 in eastern U.S.)
  • Tribs of Mississippi are the most diverse
  • Upper Ohio is least diverse of this region
  • Importance of the most recent glacial period

10
  • Tennessee River most diverse
  • Atlantic slope least diverse
  • New / Kanawha River basin relatively diverse

Reproductive Behavior
Sculpins attach eggs to underside of cobbles.
Nests are defended by solitary males until young
disperse as juveniles.
14
Reproductive Behavior
Sunfishes and basses excavate small depressions
and defend nests from predators.
15
Reproductive Behavior
Salmonids construct redds, broadcast spawn over
them, and leave eggs to the vagaries of life.
16
Reproductive Behavior
Cyprinid Spawning Mounds (probably constructed by
a central stoneroller, Campostoma anamolum)
Used by a mixed species assemblage
17
Thermal Tolerances
Cold-Water Species
Eurythermal Species
Warm-Water Species
18
Thermal Tolerances
  • Preferred / Tolerable temperature ranges vary
    dramatically among fish species.
  • Produces quasi-predictable changes in fish
    community structure along an upstream to
    downstream continuum. (spawning habitat,
    temperature, flow, food)
  • Coldwater species are highly susceptible to
    habitat degradation because most forms of
    degradation lead to higher summer temperatures.
